I'm currently printing it in PETG. Made to fit two 12mm stainless push buttons, thats what the thread is for. I intend to use those: https://de.aliexpress.com/item/10-st-ck-hochwertige-wasserdichte-IP65-12mm-momentary-push-button-switch-nicht-verriegelung-edelstahl-taster-mini/32678903625.html

You'll need 2 M4x35 screws to hold it together!
